摘　　要：纳米SiO_2作为一种被广泛应用的重要无机纳米填料,由于其吸水性较强、易于团聚,在基体树脂及有机相中相容性及分散性较差,影响了其应用性能及范围。在简述其表面结构特点的基础上,介绍了疏水性化学修饰。Nano-SiO2 is an important and widely used inorganic nano-filler. However, the performance and application range of nano-SiO2 is restricted by its poor compatibility and dispersion in the resin matrix and organic phases due to its strong water absorption and easy aggregation. In this paper, we briefly summarized the characteristics of surface structure ofnano-SiO2 and introduced some chemical approaches to modify its surface hydrophobicity.

关 键 词：纳米SIO2 疏水性 化学修饰
